The water analysis and control system is based on AquaSensors DataStick sensors networked to the Horner APG XLe Graphic OCS. The XLe Operator Control Station (OCS) is an “all-in-one" controller small enough to fit in the palm of your hand (only 3.75" square). Starting at only $295, these devices include a Graphical Operator Interface, Built-in I/O, Networking and Removable Mass Data Storage. DataStick sensors are networked over Modbus or CsCAN sensor networks to the Horner APG XLE GRAPHIC OCS. The unit supports analog and digital I/O points and is a complete programmable controller with 256 k of logic. In addition two serial ports provides for interfaces to drives, PLCs and other controllers.

Combining AquaSensors products with Horner APG’s industrial control products delivers a complete control system in a small package suitable for any water industry application from full plant to skid mounted OEM applications.

The patented DataStick modular design provides significant cost savings lowering overall cost, simplifying maintenance and calibration. DataSticks delivers flawless 24 bit resolution analog data directly over industrial networks including DeviceNet, Profibus, Modbus, Rockwell DF-1, USB, RS-232, and RS-485 to measure pH, ORP, DO, Ozone, Conductivity, Suspended Solids, and Resistivity. In addition temperature is measured with all sensors. This analog data quality is equal to or better than most DCS and process instruments deliver.

The DataStick system can be remotely calibrated, configured and diagnosed with any computer, HMI, or PLC through a single network cable. The heart of the system is the patented DataStick modular sensor system that provides a superior alternative to analog sensors. The DataStick has three basic interchangeable parts that increase reliability, simplify maintenance and lower MRO inventory. These parts are described as follows:

  • DataStick Sensor body

The DataStickTM sensor body is common to all applications and accepts DataStick sensor heads and DataStick network interfaces. The DataStick has an integrated 24-bit analog to digital converter insuring high quality data. The DataStick sensor body automatically detects the sensor head type connected to it and configures itself to send data through the DataStick network interface module.

  • DataStick Sensor Head

DataStick’s factory calibrated sensor heads are plug-and-play with any DataStick body eliminating the need for lengthy calibrations in the field. This makes it possible to have processes up and running in a fraction of the time it takes with traditional sensors. Signal loss or electrical interference from wiring is eliminated with this feature.

Maintenance and repair is greatly simplified with the DataStick’s hot swappable sensor heads. The heads can be changed without replacing the entire sensor and avoids rewiring. No more fumbling around with calibration solutions in the field, simply swap DataStick sensor heads and return to the office or lab for calibration.

  • DataStick Network Interface Modules

DataStick's Network Interface Modules provide network interfaces to popular industrial field buses including DeviceNet, Profibus, Modbus, Rockwell DF-1, USB, RS-232 and RS-485.

Integrated Sensor System

The DataStick’s measurement architecture eliminates the requirement for intermediate analyzers or transmitter boxes reducing system costs, increase accuracy, faster installation and eliminates the need to configure measurement scales after installation.

MRO inventory is reduced since Network Interface Modules and DataStick Bodies are common to all sensor heads.

DataStick sensors are designed for continuous industrial use and can be configured by the customer to measure any analytical parameter using a family of interchangeable sensor heads.

AquaSensors offers standard fitting shapes/sizes for common mounting applications; AquaSensors engineers can custom design the DataStick body to fit any shape or size of fitting. Sensor bodies are available in CPVC, 316 Stainless Steel, PEEK® and other materials.

AquaSensors LLC was established to develop revolutionary sensor design offerings using integrated digital communications, remote adjustments, interchangeable factory calibrated sensor heads and plug-and-play installation.
